Dynamic Rendering
By setting the “dynamic” parameter to True, the resulting plot will dynamically re-rasterize whenever you zoom.
v1[0][0].plot.rasterize(method="polygon", dynamic=True)
Tools
v1[0][0].plot.polygons().opts(tools=["hover"], width=900, height=400)
v1[0][0].plot.polygons().opts(tools=["hover"], width=900, height=400)
An additional tool that can be selected is the ‘lasso_selecttool, which similar to thebox_select` tool can be used to interactively select points.
v1[0][0].plot.points().opts(tools=["hover", "lasso_select"], width=900, height=400)
